We observed that peritubular myoid cells in the human testis are immunoreactive for angiotensin II (AngII) receptors (AT1R) and explored AngII actions in cultured human testicular peritubular cells (HTPCs). In response to AngII they contracted within minutes. The AT1R-blocker losartan blocked contraction, implying involvement of AngII and AT1R in(More)
In Leydig cells, hormonal stimulation by LH/hCG entails increased intracellular Ca(2+) levels and steroid production, as well as hyperpolarization of the cell membrane. The large-conductance Ca(2+)-activated K(+)-channel (BK(Ca)) is activated by raised intracellular Ca(2+) and voltage and typically hyperpolarizes the cell membrane. Whether BK(Ca) is(More)
